1) While performing the power up tests, the 'Write' LED will
normally flash for a short period, before the status indicator
flashes. This is caused by the CSM1 checking that it is able
to write to the card.
2) It is important that the SC12 connector is plugged into the
CSM1 and also into the SC532(A) or datalogger, with the
connector held perpendicular to the end of the case. If you
force the connector in at any other angle, the CSM1 may not
perform its power-up status display, although normally it
will still be able to store data. However, if the CSM1 does
not flash the status LED on power-up, it is advisable to
unplug, wait five seconds and plug it back into the
datalogger to ensure there has been a good connection.
3) If you experience problems in communicating with a CSM1
when using a PC201 card, please refer to Appendix B of the
CSMCOM manual for possible address problems and
Appendix A of this manual for details of possible problems
with the PC201 power supply.
4. Storing Data
The CSM1 emulates Campbell Scientific's SM192/716 Storage Modules for
most aspects of data storage. Therefore the same basic programs and
procedures are used to store data in the CSM1. Details of how to store data for
each datalogger type are given below.
4.1 CR10
Write your program as normal, including instructions to store data to Final
Storage. Include Instruction 96 to store data to a Storage Module, after the
output instructions. The CSM1 has a fixed address of 1 so the first and only
parameter for Instruction 96 is 71 (see Table 2 for an example program).
Under the control of the program shown in Table 2, the CR10 makes a Module
temperature measurement (in
° C) and a thermocouple measurement (converted
to ° F) every 5 seconds. Every hour, the output flag is set and the Day, Hour
and Minute as well as the hourly averages for the two temperatures are sent to
Final Storage. Following this, the same data is sent to the CSM1, if present.
If the CSM1 is not present, the data is backlogged for later transfer.
If you are using older versions of EDLOG to develop your program, entering
the code 71 for Instruction 96 will only display SM192/SM716 as the output
option. Using parameter 71 will still work with the CSM1.
